It's just a general question, popped up when i was reading a document. For instance Suppose an APN configuration of an message say Update Location Request (ULR) is not present in HSS and MME has sent the message which has reached there in HSS. What will be the reaction of HSS?

Consider UE has connected with multiple PDN connection each contains an different APN information, when we modify APN-AMBR value for both APNs at the same time in HSS and initiated HSS Initiated Subscribed QOS modification procedure, HSS sends Insert Subscriber data to MME with modified APN-AMBR information of both APN to MME, But MME forwards only first modified APN-AMBR information to S-GW in Modify Bearer Command message.
Please can anyone explain why MME does not forward second APN-AMBR information to S-GW ???. Whether the scenario is right either we can modify multiple APN-AMBR informations of single UE at the same time
